Description
BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a ballast tank provided in a ship or an air vent for venting a cargo tank, and more particularly to an air vant equipped with a liquid shutoff unit for blocking liquid from flowing into a vent .
Generally, ships operating in watercraft are widely used for transporting heavy cargo.
Large vessels are equipped with cargo tanks capable of transporting large quantities of liquids, such as oil, and can be steered by increasing the weight of the ship's bottom in order to control the draft and trim of the vessel during operation. Ballast tanks are essential.
The ballast tank is filled with ballast water to hold the equilibrium of the ship and increase the restitution force, and the cargo tank is filled with the liquid to be transported.
At this time, it is the air vent facility that allows the outside air to flow into the ballast tank or the internal space of the cargo tank.
The airbot is installed at the end where the duct connected to the ballast tank or the cargo tank is exposed to the outside, and is designed to perform pure ventilation without inflow of rainwater, seawater and various foreign substances for the purpose of inflow of outside air .
However, due to the nature of ships operating in watercourses exposed to various climatic changes, it was difficult to completely block various foreign matter from air vents to liquids such as rainwater, seawater, and creatures such as birds and insects.
Accordingly, various techniques for preventing foreign substances other than air from being introduced while ensuring air permeability have been disclosed.
The prior art relating to the packing of a marine air vant includes a technique for preventing insertion of liquid into the air vent so as to be easy to insert into a through hole formed in the air vent, Has been utilized.
However, in the related art, the floaters are raised by the buoyancy to prevent the rainwater or the seawater from flowing into the air vents. In this case, the liquid is contained in a certain space and the water surface is elevated, If a sufficient buoyancy is not applied to the plotter, there is a gap between the through hole and the inflow of seawater or rainwater can not be completely prevented.
Alternatively, a shaft for guiding the floater so as to be able to ascend and descend horizontally has to be constituted, and leakage water generated at a portion in contact with the shaft has been inevitably generated in a trace amount.
Therefore, a method for solving such problems is required.
SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems of the prior art, and to provide an air vent which is highly effective in blocking the inflow of liquid into the air vents even with a simpler structure than the prior art.
The problems of the present invention are not limited to the above-mentioned problems, and other problems not mentioned can be clearly understood by those skilled in the art from the following description.
According to an aspect of the present invention, there is provided a marine air vant having a hollow air vent head connected to an end of a duct and having an opening on one side thereof, And a floating valve which is located in the compartment and the compartment through which the outside air flows into the compartment and which is raised and lowered by the buoyant force to close the ventilation hole formed on the upper surface of the compartment by a magnetic force, And flows into the duct via the inner space of the air vent head.
Alternatively, the floating valve may include a magnetic attachment portion formed by protruding a central portion upwardly and gradually becoming thinner toward the outer periphery, and formed of a material having magnetism at the upper portion, and formed of a material having magnetism around the ventilation hole And a magnetic coupling portion that is magnetically coupled with the magnetic attachment portion.
The bumper further includes a packing bumper disposed on a surface where the magnetic attachment portion and the magnetic coupling portion are in contact with each other and formed of a rubber material.
Alternatively, the floating valve is provided with a plurality of balance holes formed vertically through the edge at regular intervals.
The balance holes are formed to be inclined in the same direction.
Alternatively, the air vent head is provided with an inspection port formed on the upper surface so as to be openable and closable at a position corresponding to the ventilation hole, and the ventilation hole is opened by pushing down the floating valve closing the ventilation hole by the pressure bar inserted through the inspection port.
The compartment is formed on the lower side, and has a drain hole for discharging the fluid inside.
In order to solve the above problems, the present invention provides an air vent for a ship, which closes a ventilation hole in an air vent, and has a large effect of preventing the inflow of liquid because the air valve is attached airtightly by magnetism, There is an effect.
